In the diagram below, A, B, C, D are four pendulums suspended from the same elastic string PQ. The length of A and Care equal to each other while the length of pendulum B is smaller than that of D. Pendulum A is set into a mode of vibrations.

What is the state of pendulum C?

Text Solution

Verified by Experts

Pendulum C is in a state of resonance with Pendulum A. Also they are in the same phase.

The figure below shows a simple pendulum of mass 200 g. It is displaced from the mean position A to the extreme position B. The potential energy at the position A is zero. At the position B the pendulum bob is raised by 5 m. (i) What is the potential energy of the pendulum at the position B? (ii) What is the total mechanical energy at point C? (iii) What is the speed of the bob at the position A when released from B ? (Take g = 10ms^(-2) and there is no loss of energy.)

A large number of pendulums with identical bobs (mass m) but varying lengths are suspended from a thick thread. Another pendulum of a heavier bob (mass M) is also suspended from the same thred as shown. This pendulum with the heavier bob is used as a 'driver' to drive the other pendulums called as 'driven' pendulums. Assume that the amplitude of the driver is maintained constant (by some suitable mechanism). Let the frequency of the driver be f_(0) The above pendulum is set into oscillation with an initial amplitude of 10.0 cm. Soon this pendulum comes to rest momentarily and the driver is seen to oscillate with an amplitude of 8.16 cm. Then mass M equals

A block suspended from a vertical spring is in equilibrium. Show that the extension of the spring equals the length of an equivalent simple pendulum, i.e., a pendulum having frequency same as that of the block.
